Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile construction, specifically to a shallow sea steel pipe pile driving construction system. Background Technology

[0002] Steel pipe piles are the first step in the construction of steel trestle bridges and also the main load-bearing structure. The height differences caused by the ebb and flow of tides in shallow sea waters greatly affect the positioning of the steel pipe piles. At the same time, the complex and variable weather conditions in the marine environment also significantly restrict the construction progress of the steel pipe piles. Traditional steel trestle bridge piling systems using the fishing method require inserting piles into existing steel trestle bridges and continuously extending the working area. Given the tight schedule and complex and variable marine environment, this method cannot quickly open up the working area or achieve simultaneous multi-point operations, clearly failing to meet the urgent needs of the construction schedule.

[0003] In summary, there is an urgent need to propose an effective solution to achieve multi-point synchronous operation in the sea area, ensure the accuracy of steel pipe pile positioning in shallow waters, and accelerate the overall construction efficiency of steel pipe piles. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes a shallow-sea steel pipe pile driving construction system, including a floating crane, a vibratory hammer, steel pipe piles, and a vertical guide frame; the vertical guide frame includes a bottom crossbeam, a middle crossbeam, a top crossbeam, a vertical column, a top longitudinal beam, horizontal braces, positioning frames, and a bottom longitudinal beam; the bottom longitudinal beam and bottom crossbeam are both located at the lower end of the vertical column, and the top crossbeam and top longitudinal beam are both located at the upper end of the vertical column; multiple positioning frames are provided at the upper and lower parts of the vertical guide frame; the upper positioning frames are positioned directly above the lower positioning frames; the positioning frames are circular, and the positioning frames are connected by horizontal braces; when the vertical guide frame is placed on the seabed at the construction location, the top of the vertical guide frame is higher than the seawater level; the vibratory hammer is mounted on the sling of the floating crane.

[0006] Preferably, inter-column bracing is provided between the bottom longitudinal beam and the top longitudinal beam.

[0007] Preferably, the bottom crossbeam of the vertical guide frame is longer than the top crossbeam.

[0008] Preferably, a diagonal support is provided between the bottom crossbeam and the vertical column.

[0009] Preferably, the inner diameter of the positioning frame is 1.05-1.1 times the outer diameter of the steel pipe pile.

[0010] The beneficial effects of this utility model are as follows:

[0011] (1) This utility model uses a floating crane in conjunction with a vertical guide frame to carry out shallow sea steel pipe pile driving operations. The vertical guide frame is pre-placed in the water, and the steel pipe pile is inserted into the positioning frame in the vertical guide frame and driven by a vibratory hammer, which improves the accuracy of steel pipe pile driving.

[0012] (2) The vertical guide frame developed by this utility model is equipped with multiple positioning frames, which can meet the positioning of multiple steel pipe piles at one time, thereby improving the pile driving efficiency of steel pipe piles.
